As of the 2010 census, the city had a population of 25,719.[7] Xenia is the third largest city by population in Greene County, behind Fairborn and Beavercreek. It serves as the county seat of Greene County, being at the geographical center, and housing the County Courthouse, the County Sheriff's Department, Jail, and other Government departments. By population, it is the largest place in the United States whose name begins with the letter X.

Xenia was founded in 1803, the year Ohio was admitted into the Union. In that year, pioneer John Paul bought 2,000 acres (8.1 km2) of land from Thomas and Elizabeth Richardson of Hanover County, Virginia, for "1050 pounds current moneys of Virginia." Paul influenced county commissioners to locate the county seat on this land at the forks of the Shawnee Creeks.

Joseph C. Vance was named to survey the site and lay out the town. The following year, he bought the town site of 257 acres (1.04 km2) from John Paul for $250. The name of the new village was chosen in typically democratic fashion. Vance called a town meeting to discuss possible names. The committee had considered several suggestions without reaching any decision. Then the Rev. Robert Armstrong proposed the name "Xenia," meaning "hospitality" in Greek, because of the fine hospitality extended to him in this friendly community. When a tie vote occurred, Laticia Davis, wife of Owen Davis, was invited to cast the deciding ballot. She voted for "Xenia."

William Beattie was Xenia's first businessman. In 1804, he opened a tavern which became a center of community affairs. In 1804, John Marshall built Xenia's first home. The first log school house was constructed in 1805, and, that same year, the Rev. James Towler became the town's first postmaster. The growing community soon attracted many pioneer industries - flour mills, sawmills, woolen mills, pork packing plants, oil mills, and tow mills.

President-Elect Abraham Lincoln made a brief appearance in the city as his inaugural train traveled from Cincinnati to Columbus on Wednesday morning, February 13, 1861. He gave a short speech which was not recorded by a traveling writer from the New York Times as it echoed the same sentiments that he had expressed before in his previous stops. According to the Times writer, "a very large crowd assembled, and amid the firing of a cannon and enthusiasm, Mr. Lincoln addressed them from the rear car, reiterating what he had said before.".[8]

The town progressed rapidly during the mid-19th century. Artificial gas was provided in the 1840s and continued in use until natural gas was made available in 1905. The first fire engine house was built in 1831; the telephone came to Xenia in 1879; electricity in 1881 and a water works system in 1886. Xenia opened its first free public library in 1899. By 1900 the city was operating its own sewage system.

Xenia elected Cornelius Clark as its first mayor in 1834. On January 1, 1918, the current commission-manager plan succeeded the old form of municipal government.

Xenia has a history of severe storm activity. According to local legend, the Shawnee Indians referred to the area as "the place of the devil wind" or "the land of the crazy winds" (depending upon the translation).[9] Records of storms go back to the early 19th century. Local records show 20 tornadoes in Greene County since 1884.[citation needed]

Xenia tornado on April 3, 1974

On April 3, 1974 a tornado[10] rated F5 on the Fujita scale cut a path directly through the middle of Xenia during the 1974 Super Outbreak, the second largest series of tornadoes in recorded history. The disaster killed 34 people (including two Ohio National Guardsmen who died days later in a related fire), injured an additional 1,150, destroyed almost half of the city's buildings, and left 10,000 people homeless. Five schools, including Xenia High School, Central Junior High School, McKinley Elementary, Simon Kenton Elementary, and Saint Brigid Catholic School were destroyed, as were nine churches and 180 businesses.

The city's plight was featured in the national news, including a 1974 NBC television documentary, Tornado!, hosted by Floyd Kalber. President Richard Nixon visited stricken areas of Xenia following the devastation. Comedian Bob Hope organized a benefit for Xenia and, in appreciation, the new Xenia High School Auditorium was named the "Bob Hope Auditorium." In recognition of their coverage of this tornado, the staff of the Xenia Daily Gazette won the Pulitzer Prize for Spot News Reporting in 1975.[11]

Xenia was struck by an F2 tornado on April 25, 1989 and again by an F4 tornado on September 20, 2000. The 1989 tornado caused over $2 million in damage, but no one was killed. The twister of 2000 killed one person, and injured 100 people. This tornado followed a path roughly parallel to the 1974 tornado.[12][13]

Xenia currently has a system of tornado sirens. After the 1974 tornado outbreak, the city purchased a system of Federal Signal Thunderbolt Sirens for warning. During the 2000 tornado strike, the lack of backup power silenced the sirens, so the city purchased Federal Signal 2001-SRN series sirens with battery backup. Most of Xenia's old sirens are still standing, but not operational.[citation needed]

The roadbeds of five of Xenia's six rail lines were converted for rail trail use. The one exception — the B&O line west of town — was not converted because it closely paralleled the PRR mainline for most if its length. The large number of rail trails resulted in Xenia being referred to as the Bicycle Capital of the Midwest.[14]

Xenia is centrally located in the "transportation triangle" formed by three major interstate highways: I-70, I-71, and I-75. These north-south, east-west arteries are within minutes of Xenia via U.S. Routes 35, 42, and 68, tying the community to one of the nation's largest 90-minute highway markets. Before the creation of the U.S. Interstate Highway system, U.S. 68 was one of the main southward routes from Detroit, Michigan. Within Xenia, U.S. 68 is named "Detroit Street".

According to the United States Census Bureau, the city has a total area of 13.29 square miles (34.42 km2), of which, 13.28 square miles (34.40 km2) is land and 0.01 square miles (0.03 km2) is water.[1]

The Xenia City Council exercises the powers and authority of a municipal corporation as determined by the constitution of the State of Ohio and the Charter and ordinances of the City of Xenia. The City Council of Xenia, Ohio, is composed of seven elected council members, including one mayor. Council members are each elected for one four-year term of office.

Maynard James Keenan mentions Xenia at least twice with his band Puscifer, first in "Sour Grapes (Where is the Line Mix)", and again in a fictional documentary played before shows on their 2011 tour. The Puscifer Characters Billy Dee Burger and Hildy Burger are credited as being from Xenia.
